Hum from line conditioner?

I have isolated a hum from both speakers to my line conditioner. Does the AudioPrism Foundation III have any internal parts that can fail?

Two other causes maybe? The line conditioner power cable causing interference or, the LC positioned too close to one of my amps, 8"...

A cheap Costco surge protector I have swapped is dead silent!

Any thoughts?

It probably has a noisy transformer that needs to be replaced.

A dedicated circuit is great but may not alleviate the ground loop. You will probably have to break the ground on the device causing the loop. The culprit is usually cable or satelite TV. It's odd that the hum didn't occur when you were only using the inexpensive surge protector. Did you connect all of your equipment to it?
